The Lean Protocol is a two-compound research bundle combining Retatrutide 10mg and Tesamorelin 10mg — two metabolically active compounds studied for their complementary effects on body composition and lipid metabolism.

Retatrutide 10mg Retatrutide is a triple GIP/GLP-1/glucagon receptor agonist studied for its effects on energy intake, lipid metabolism, glycaemic control, and body composition. Its simultaneous engagement of three incretin-related receptors produces a broader metabolic profile than single or dual agonists.

Tesamorelin 10mg Tesamorelin is a stabilised GHRH analogue studied for its ability to stimulate GH secretion and downstream IGF-1 production. It has been specifically investigated in research examining visceral adipose tissue reduction, lipid profile modulation, and metabolic syndrome models.

Why this combination? Retatrutide and Tesamorelin approach metabolic regulation via distinct but complementary pathways — incretin receptor agonism modulating energy intake and glucose handling, GHRH-mediated GH secretion influencing visceral fat and lipid metabolism. Together they provide a multi-pathway research tool for metabolic syndrome and body composition studies.

Before reconstitution: store at room temperature away from direct light. Stable at ambient temperatures prior to reconstitution.

Reconstitution: add bacteriostatic water slowly to the vial using a syringe. Swirl gently — do not shake. Use our Reconstitution Calculator for the correct volume.

After reconstitution: refrigerate at 2–8 °C. Avoid freeze-thaw cycles. Use within 28 days.
